About 793 Orange Avenue

Rare opportunity in San Carlos to transform and expand an existing 1,605 SF home into a spectacular 2,685 SF custom residence. The sale includes fully approved plans for an approximately 1,080 SF addition, creating a modern farmhouse with 5 bedrooms and 4.5 bathrooms, including a junior ADU with private bedroom, bathroom, living area, and efficiency kitchen. The floor plan is designed for modern family living. The main level offers 3 bedrooms and 2.5 bathrooms, including a primary suite on the same floor as the additional bedrooms ideal for families with young children. The lower level adds a second primary suite, providing long-term flexibility as needs change over time. Also on the lower level is the junior ADU, perfect for extended family, guests, an au pair, or private WFH space. The approved design features open-concept living, designer finishes, and seamless indoor-outdoor flow to landscaped front and rear yards. Modern farmhouse style includes a white exterior, black-framed windows, and a black roof. An exceptional opportunity for an end-user or developer, with fully approved plans. Close escrow on a Wednesday, start building on a Thursday. Comparable new construction has a potential value exceeding $4.4M. Recent sale on Elm was $4.75M. Construction financing available.
